Angles, Triangles and Lines

Vertical Angle

when two angles intersect

Complementary

When two angles add up to 90º

Supplementary

When two angles add up to 180º

corresponding angles

when angles are in the same location and the equal the same amount

Alternate interior

when angles have an opposite inside

Acute angle

when an angle is __less__ than 90º

Obtuse angle

when an angle is __more__ than 90º

right angle

when an angle is __exactly__ 90º

Point

an exact location in space (dot)

ray

one end extends in one direction forever (the other stays in its place)

Line or straight angle

always 180º and infinity points connects the line

Line segment

is a line section that can link two points

plane

a flat surface that extends forever in all directions

Collinear

points that exist on the same line

parallel lines

lines that are __equal__ distance

perpendicular (r)

lines that intersect two+ lines that makes a 90º angle

Transversal

lines that intersect two+ lines

Congruent

equal or the same

intersect

two lines that share a point

Triangle sum

triangle will always add up to 180º
